Q:

Find all values of x that are NOT in the domain of h.If there is more than one value, separate them with commas.h(x) = x + 1 / x^2 + 2x + 1

Accepted Solution

A:
Answer:if x=-1 then its is NOT in the domain of h.Step-by-step explanation:Domain is the set of values for which the function is defined.we are given the functionh(x) = x + 1 / x^2 + 2x + 1h(x) = x+1 /x^2+x+x+1h(x) = x+1/x(x+1)+1(x+1)h(x) = x+1/(x+1)(x+1)h(x) = x+1/(x+1)^2So, the function h(x) is defined when x ≠ -1Its is not defined when x=-1So, if x=-1 then its is NOT in the domain of h.
